The relationship between hyperlipidemia and physical activity in the elderly after controlling for demographic, health, and lifestyle variables

In China, the number of elderly people with high blood lipids is increasing, and it is crucial to find practical methods to reduce the risk of high blood lipids in the elderly. This study explores the relationship between physical activity (PA) and hyperlipidemia in middle-aged and elderly people in China, providing new evidence for the prevention and treatment of hyperlipidemia through PA. This study investigated the association between PA and hyperlipidemia in 1779 middle-aged and elderly Chinese individuals. The Charles database from 2018 is the source of the data. This survey used a self-made personal information questionnaire, the Chinese version of the international PA questionnaire, and a self-assessment questionnaire for high blood lipids and personal information to evaluate the levels of high blood lipids and PA. Multiple logistic regression analysis is used to identify risk variables for hyperlipidemia and PA, while multi-level linear regression analysis is used to evaluate the correlation between PA and the likelihood of hyperlipidemia. The detection rate of hyperlipidemia symptoms was 13.4%, and the asymptomatic detection rate was 86.6%. 43.8% of people engage in high PA, while 50.2% engage in low PA. There is a significant correlation (P < .05) between PA and symptoms of hyperlipidemia in middle-aged and elderly people. After adjusting demographic variables (residence, education level, gender, age, widowhood or not), health status characteristics and living habits (arthritis, bad mood, diabetes, disability, asthma, self-assessment health, memory disease, stroke, depression), the correlation between PA and hyperlipidemia symptoms was still statistically significant (P < .05). The strong association between high blood lipids and PA provides information for developing targeted therapies for elderly individuals with high blood lipids in order to ensure efficacy and inclusiveness, improve PA levels, enhance the mental health of the elderly, reduce their risk of hyperlipidemia, while taking into account certain demographic and lifestyle characteristics.
